Cushion heel

Application .filed February l?. 1320.

Be ity known that l. Tinmfxs ill. Coeonln :l` Acitizen oi the United filetes. residing at vElyria, in the eonnt'i' ol Lorain7 Stute of Chio. have invented certain nen' zrnd use- Vl'ul improvements in Cushion Heels; und l do herebi7 ler-lure the following to be e. tull. clear7 und exact description oi the invention, such as will enable others skilled in the nrt to which it eppertziins, to make and use the sume.

rihis invention relates to boots nnilshoes and more especially to those, deviees known as cushion heels; and, its purpose is to produce :L lift oi' soft materiel such ns ruhber or rubber eon'position. capable ot being applied to the rigid or leather portion oi' the heel or in some eases to the sole itself7 to give the article ot :toot weer certain ndrnnlnges' which are peculiar to this invention such :is nre set forth below.

The primary ohjeet oi' 'the invention is to render the heel so'lt in tiro ways so as to Ineke Walking very easy to the wearer. lo

' this end the heel is perth/J pueunnitir and partly Cushioned, or more speriiienlly its margin-nl port-ion solid butv oiI yiellline' or eonipressible materiel whereas eentrul portion contains an nir pocket und protrudes on. its trend 'hire beyond the. innib'in of the tread so that, when the heel is put down the Weight of the wearer is .first resisted by snidv )neuniutie portion :rnd then by the eushion portion .Vhieh strikes the ground when the protuberant portion hns been depressed. and thus sniil Weight iserenlunlly sustained by all ports oli` the heel.

Another importznot object of the invention is to provide the fleriee with nnti-sliid ttes.- tures. As set 'forth herein this is aieeonr plishefl byv dishing' the nmrg'innl portion ot its trend inward, or in other words inelining it outward, and Lliorniin;l ai. salient and pre i'- erably acute angle between it und the eilgie. o-l the lift1 along' that line Whirh will be the periphery of said margin and therefore the. leripher" ot the entire treed. lilvhen the heel strikes the ground, the pneumatic. portion is first. emnpresseil. and then the cushion portions strikes the ground es above slated, but strikes the ground iirst along the Vortex of this peripheral nente :ingle rather thu along the entire linee ol the nizirginnl portion. and sueh :infile has u rertnin iV-ling which prevents slipping.

A. further object of the invention is to imserial no. 359,271.

proie the ineens for producing the air pocket Within seid pneumatic portion. rl`his is no eoniplished by making n cavity utfthe center ol the upper or inner rare ot' the soft. litt, und entireliv surroiunling such Cavity by .fi channel in such linee, the rhennel heine' dei'ined by :fi ridge between it und the pocket, 'und byu margin; and then When the litt is 'feste-ned to the heel by screws or `the like which pass directly through the channel and nre set up tight, the ridge and the margin are both drawn against the leather heel so that, plural points of Contact are formed be-- iueen the heel and the littl and the air is eeret'ully trapped in the pocket `which is orodueed by the fiat heel and the (lished or ehinnbered inner face of the litt.

Other features of the invention will zippeur in the Alollowing` speeiieat-ion which Al'erth one successful manner of eerrving out the iden7 and reference is; mede to the filmtving's wherein:

Figure l is :i perspective View of this strueture lie'tore its application to the shoe..

Figure 52 u seetional View showin;r the strnrture applied und indicating in dotted lines the position ot parts :liter the heel has come into roulant with the `around.

ln illigure the letter lli designates the heel ot e hoot or shoe7 usually Inode in lifts ol' leather nailed together. loutthis is for* illnstrntirx purposes only? as the invention might hi, applied directly to the heel portion ot' the sole oi s hoot or shoe. The structure forming0 the subject metter oi? this in rention is shown detnehed in Figure l, and, is in efieet :i (rather thiol() liiit composed of ilexihle or elastic material such :is rnbher or ruhber Compound, uniform 'in consistency throughout or not es preferred7 made in any suit-able manner and ol proper size. or possibly in several sizes to (it filifierent heels and applied und fastened, :is hereinafter set forth. lt niight he here stated than; its thickness :1nd its transverse dimensions are nmtters o no importance to this ini'ention. but by pre-.terence the rubber heel tapers downward on its edge :is seen7 or in other words flares upward so that its upper or inner eorner l is quite pronoinu'ed and will underlie n heelll or good size. buty this corner muy be pared ofi ensil)v to fit snmllerheels wiihout seriouslyY inipziiring the downward taper of the edge 2. For this purpose szlitl edge is preferably given e slight uprinlit dish, und this dish may prevail across the lll) lli

breast 2S of the heel, which as usual has also a transverse dish. For purposes ot description We will herein call the rubber lift a heel, since it may constitute the entire heel or the lower and active portion ot a leather heel. ln the latter case one or two litts of leather are removed and the rubber heel applied by passing screws el upward through washers 5 which r re seated in sockets formed in the outer face o't the heel. and then t'oreiirgT the screws through holes 7. through the body of the rubber and upward into the leather shown at 8 in Figure El; und when these screws are set up tight the of the rubber and leather are drawn into close be deseribed.

The upper face of this improved heel is moulded or otherwise formed'with a dished or cupped center producing a cavity 10 ot considerable Size, around which is a ridge ll; around the ric ge is a channel '1 2 intersected by the holes 7 through which pass the screws 4, and around the channel in turn .is a margin 13 Wheh flares' outward tothe peripheral angle l. The cavity is somewhat deeper than the channel, and when the ifs are set up tight the faces of the inarand ridge are dra-Wn into elose Contact the lower face ot' the heel H, and the y l() becomes an air chamber or pocket, .i air trapped therein being reliably re tainedI first by the Contact of the ridge with the heel l and second by Contact of the margin with the heel H, the outward flare of said 'margin making the Contactbetween its outer edge and the heel very pronounced. .it its corner is thereby urged beyond the edge of the heel as seen in Figure 2, it may loe pared oli to produce a neat finish. Fig ure l shows live of the holes 7, but I desire not to be limited in this respect; also it is clear that other fastening means might be employed in the place of or in additionto the screws, and it is quite possible that a layer of cement between the contacting rubber and leather portions would seal the air pocket absolutely tight.

The outer or lower face of the heel con stitutes its tread. As seen in Figure f2, this tread is made up ot' an arched or protuheraut central portion 20, and a marginal portion 2? the margin being` dished inwart from, the peripheral corner or' angle .21 to a line 22 where said margin unites with the central portion: or Vin other words, Athe tread comprises a central portion 2() Surrounded by' a rhanuel 2:?, and that in turn surrounded oy a margin 23 which extends to the periphvv Eecause the margin 23 iaree outword and the 2 of the heel is Aot the shape shown, ay salient is prf Contact for a purpose which will' Meeres the periphery, preferably au aou which will have a certain cling on ii Surfaces and therefore constitu slrid-t'eature. The sockets (l ai formed in tl e channel 22, and this terred although not essential.

lillhen the. wearer places his heel the ground, the central portion (which protrudes on account both its shape an Y' First l the existence of the air pocket) str' the ground on the line G; u" ou heel compresses the eentru.. portion und the air Within the pocket l0 so that the parts assume the position shown in dotted lines` or in other words the ground line ll and contacts with the peripheral angle and the anti-skid feature cornes into play;

lt is to be understood that minor #hanf may be made so long :is the spirit oit the in vention is retained. o@
